2-whenever my dashboard is called the report is now cached from myreport1.rptdocument

But what i have experienced is that the frameset-servlet is very slow (uses 3-6 seconds to show the result).
If i use the preview-servlet with the __document parameter it shows it under a second. A lot quicker.

But the problem is that the preview-servlet does not generate a rptdocument, it can only show a report. Is there a smart way that i in my dashboard
check if a rptdocument exists, if not call the frameset servlet to generete the rptdocument. And the next time always call the preview-servlet ?
